Cured Covid for me in less than 24 hours. Unbelievable I know.
The book is a must, if you can find it. Kalcker has studied chlorine dioxide for 13 years now. It's an amazing product.
I now drink it every day and my overall health both mentally and physically has improved.
Don't believe all the negative stuff out there that says, you'll go blind. It's all false, this book will prove it.
